It doesn't take much to bring Kate
down to earth.
After days of buoyant Diamond Jubilee celebrations
for Queen Elizabeth, the Duchess of Cambridge slipped into something more comfortable – jeans, Barbour jacket and a hat – and stepped out for a walk through Kensington Gardens with her dog Lupo, her younger brother James Middleton
, and another dog, presumed to be a Middleton family cocker spaniel.
The siblings were spotted last week by Canadian TVjournalist Jocelyn Laidlaw in a chance sighting at Kensington Gardens in London.
"Catherine Duchess of Cambridge walking Lupo today in Kensington Gardens," Laidlaw wrote
. "Lovely to see her so low-key. What luck."
A video posted by Laidlaw shows the Middleton pair walking briskly through the park, largely going unnoticed and left undisturbed. Both dogs trot along off-leash but stay close.
Kensington Gardens, a Royal Park of London, has been a go-to walk for the Duchess and her cocker spaniel puppy, who have been spotted
on other occasions getting some fresh air on the grounds.
